Inventor: HANEDA SHOJI
IPC: H02M7/21
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain a rectifier and a full-wave rectifier having a small loss and large breakdown strength. SOLUTION: When a voltage is not applied between the emitter-collector of a transistor Q3 and the potential at the collector is higher than that at the emitter, no voltage drop appear across a resistor R1 and transistors Q1, Q2 and Q3 are turned off. When the potential at the collector of the transistor Q3 is lower than that at the emitter, a voltage drop appear across the resistor R1 and the transistors Q1, Q2 and Q3 are turned on. When the current between the emitter-collector of the transistor Q3 increases, voltage across the resistor R1 increases to cause increase in the collector current of the transistors Q1, Q2 and Q3 and the voltage between the emitter-collector of the transistor Q3 decreases.

Title: Method and device for straightening metallic thin wire
Inventor: NAGAI HIROSHI
IPC: B21F1/02
Filed: 1984-02-21
Abstract: PURPOSE:To secure high straightness by hooking a metallic thin wire to the outside and the inside, respectively, of each roll placed on the upper, middle and lower stages placed zigzag in each stage of the former period of the latter period of straightening giving large and small plastic bending and rebending, and straightening distortions such as torsion, bend, etc. of the metallic thin wire. CONSTITUTION:A metallic thin wire is straightened by a roller 2 which has a groove bottom diameter 10-50 times a wire diameter of the metallic thin wire and is placed zigzag on the upper, middle and lower stages. That is to say, for instance, large bending is given to the metallic thin wire by the roller 2 of #3, #4, and #5, as shown in the figure A. Subsequently, this metallic thin wire is bent reversely to a bending way of the roller 2 of #3 by the roller 2 of #2, and also bend is given to the same direction as the roller 2 of #3 by the roller 2 of #1, by which the straightening is completed. As a result, torsion in the course of straightening the metallic thin wire is prevented, and bending can be given up to a part which is near the center part of a material. Accordingly, the straightening which has applied a tensile force can be executed, and also the straightening is adjusted easily. In this regard, even when methods shown in the figures B, C are adopted, the same effect is obtained.
